Preliminary Data Sheet

BCM5222

Dual Port 10/100BASE-TX IEEE 802.3u Fast Ethernet Transceiver

GENERAL DESCRIPTION

FEATURES

The BCM5222 is a dual-port, low-power, 10/100BASE-

TX transceiver targeting a number of applications

requiring intelligent power management and robust

network tolerance. The BCM5222 operates using a 1.8V

and 3.3V supply. The devices contain two full-duplex

10BASE-T/100BASE-TX Fast Ethernet transceivers,

which perform all of the physical layer interface functions

for 10BASE-T Ethernet on CAT 3, 4, and 5 unshielded

twisted pair (UTP) cable and 100BASE-TX Fast Ethernet

on CAT 5 UTP cable.

•

Dual Port 10/100BASE-TX IEEE 802.3u Fast

Ethernet Transceiver

•

Power Consumption: <180 mW/port

Unique Energy Detection Circuit to Enable Intelligent

Power Management

Cable Length Indication

Cable Noise Level Indication

Cable length greater than 140 meters

Well Under 10 PPM defect ratio quality

Industrial Temperature Range (-40 to 85C)

MII/7-wire serial interface

The BCM5222 is a highly integrated solution combining

a digital adaptive equalizer, ADC, phase lock loop, line

driver, encoder, decoder and all the required support

circuitry into a single monolithic CMOS chip. It complies

fully with the IEEE 802.3u specification, including the

Media Independent Interface (MII) and Auto-Negotiation

subsections.

IEEE 1149.1 (JTAG) Scan Chain Support

MII Management Via Serial Port

100-pin PQFP and 100-pin fpBGA packages

APPLICATIONS

The effective use of digital technology in the BCM5222

design results in robust performance over a broad range

of operating scenarios. Problems inherent to mixed-

signal implementations, such as analog offset and on-

chip noise, are eliminated by employing field proven

digital adaptive equalization and digital clock recovery

techniques.
